In Figs. 7 to 9.various constructional forms are represented, in all of which, in common ith that above described, the ejector is fixed to the wall of the breech-casing, and one'of the extractors holds the cartridge-case firnily untilit is ejected, the other extractor releas tractors, both of which coopcrateto nai'n tain the cartridge inan axial position until its base has nearly reached a fixed ejector or other glixed stop, whereupon the second hr auxiliary extractor is moved away from the rim of the cartridge by the ejector or other fixed stop, so that the eartridgecase strik ing against the ejector is caused to tilt or turn around the other extractor and therc by ejected from the breccincasing.

In. the accompanying drawings, Figure l is a horizontal longitudinal section through the breech, showing the cartridge already extracted from the barrel, but still held a ly. Fig. 2 is a similar section shoi'ving the coinmcncemcnt of the ejection Fig. 3 is a crosssection through the gun-casing and shows theejector and the ejectorropening. Fig. l shows various views of the head or hreech piece of the reciprocating breech-block 6. Fig. 5 shows various views of the movable auxiliary extractor. Fig. 6 shows simi a views of the usual extractor. Figs. 7, 8, and 9 illustrate modifications of details.

Both the extractors 1 andv 2 are placed in recesses and l of the bree clupiece 5 and remain thereinsecure from accidental displacement when Qie said breech-piece is attached to thebrcecheblock 6 by its bayonet-joint: The'extractor 1 is of the usual form; butthe auxiliary extractor is provided with two the cartrid *e-ca'se by the ejector or by some other fixe stop before the cartridge-case strikes against the said ejector.
